Given numbers are 65, 47, 19

The list of prime factors of all numbers are

Prime factors of 65 are 5 x 13

Prime factors of 47 are 47

Prime factors of 19 are 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 65, 47, 19

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(65, 47) = 3055

GCD(65, 47) = ( 65 x 47 ) / 3055

= 65 / 47

= 65

Step2:

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

= 1 / 19

= 1

So, Greatest Common Divisor of 65, 47, 19 is 1
